[petsc-users] MUMPS error

[siddhesh godbole]

Hello,


i wanted to use mumps package for parallel direct linear solver in my
spectral transformation call to ksp during EPSSolve. i ran this command as
per section 3.4.1 in slepc guide. though this message tell me that i need
to download mumps i still see the mumps package in my
petsc-3.5.2/src/mat/impls/aij/mpi directory.
how do i resolve this error?

-st_pc_factor_mat_solver_package mumps*
